SPECIFICATION forming part of Letters Patent No; 727,995, dated May' 12, 1965. Application filed January 7, 1903. Serial No. 138,097: (No model.)

T0. (0% whom zit may concern:

Be it known that I, FREDERICK OLSON, a citizen of the United States, residing at Calumet, in the county of Houghton, State of Michigan, have invented a Machine for Clean ing Flues; and I do declare the followingto be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form a part of this specification.

My invention has relation to fine-cleaners and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of my invention is to provide a flue-cleaner of simple construction and durable nature and adapted to be easily operated.

The cleaner maybe located permanently in the fine without interfering with the draft thereof.

In the accompanying drawings, Figure 1 is a top plan View of one form of the'support for the flue-cleaner. Fig. 2 is a transverse sectional view of the form of support for the flue-cleaner. shown in Fig. 1. Fig. 3 is a top plan view of another form of support for the flue-cleaner. Fig. 4 is a sectional view ofthe form of cleaner-supportshownin Fig. 3. Fig. 5 is a side elevation of the flue-cleaner. Fig. 6 is a top planview of the flue-cleaning device provided withbrushes. Fig. 7 is aplan View of one of the plates for securing the fluecleaning device, and Fig. 8 is a sectional viewof the plate shown in Fig.7.

The device consists oft'h e top piece 1, which may be secured in the upper part of the chim ney, as shown in Fig. 4, or'thesaid top may be provided at each end with angle. exten sions 2 2, which are adapted to pass along the sides of the chimney, the thumb-screw passing through one of said angle extensions and bearing at its inner end against the side of the chimney and holding the top piece in position. In the form of the invention as shown in Figs. land 2 the middle of the top piece 1 is provided with the upward extension 4, along the middle of which and in alinement with the longitudinal axis of the top piece 1 is provided a channel 5, the ends of which pass through the top piece 1 and terminate in the under side thereof, the side walls of the said channel 5 forming guides for the chain that supports the cleaning device, as will be hereinafter described. The portion 6 of the top piece 1, located below the channel 5, is se'micylindrical along its upper surface.

In the form of the invention as shown in Figs. 3 and e the extension 4 projects down instead of up, as shown in Figs. 1 and 2; but the location of the channel and central solid portion 6 of the top piece is substantially the same as that described, as shown in Figs. 1 and 2.

The cleaner proper consists of the parallel bars 7 7, the outer ends of which are connected by the cross-bars 8, to which may be secured bristles 9, said bristles being made of metal or any other suitable material. The bars 7 and 8 are arranged as shown in Fig. 6, and the threaded shank of the hook 9 passes through the central opening between the inner ends of the bars 7 7: The plate 10 is interposed between the shoulder 11 of the said hook and the upper surfaces of the said bars 7 7 and a similar plate bearing against the under surfaces of the said bar 7 7, the parts being held together by the nut 12, which is screw-threaded uponthe shank of the said hook. One end of the chain 13 is linked to the said hook 9', the said. chain passing up and over the solid semicircular portion 6 of the top piece 1. The chain then descends and passes through the space between the bars 7 7 of the cleaning device, the lower end of the chain being linked to the lower end of the shank of the hook 9.

The device may be constructed to operate in fines of various shapes and sizes, and it will not damage the lining of the due when in operation.

To'operate the device the operator pulls alternately at either side of the chain, and thus causes the cleaning bars or brushes to pass the entire length of the flue, anda thorough cleansing is accomplished. The apparatus can be left hanging in-the flue ready for use and can be easilyremoved after the flue is cleaned.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A flue-cleaner comprising a top piece adapted to be secured to the flue, said top piece having a channel located therein and extending in alinement with its longitudinal axis the portion of the top piece below the said channel being stationary and having a semicylindrical upper surface and the ends of the channel passing through the said top piece, a chain adapted to pass through said channel and over the semicylindrical surface of the stationary solid portion of the top piece and a flue-cleaning device carried by said chain.

2. A flue-cleaner comprising a top piece havingachannelextendingin alinement with its longitudinal axis, the ends of said channel terminating in the under side of the top piece, the solid portion of the top piece located below the said channel having semicircular upper surfaces, angle extensions located at the ends of the top piece and adapted to pass along the edges of the flue, a setscrew located in one of said angle extensions and adapted to bear at its inner end against the side of the fine, a chain adapted to pass over the solid semicircular portion of the top piece and a flue-cleaning device carried by said chain.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses.

FREDERICK OLSON.
